IMPROVED SODA-WATER APPARATUS.

Specification forming part of Letters` Patent No 40,8l l. dated Decmnlwr cl, ic'o.

My invention relates to improvements in the details and arrangement of soda apparatus by which the manipulation required in preparing beverages is reduced in amount and the quali-ty of the beverage is improved, and by which increased speed of preparing them is attained.

My invention consists in concentrically, or

v'nearlysm 'arranging around a central orifice or orifices, but separate therefrom, other ori-v ices through which may be drawn sirups or other fluids used in the preparation of effervescing beverages; also, the employment, in a soda apparatus, of a device by which soda may be drawn from one common source through two different deliveries withrbut one manipulation on the part of theloperator; also, the arrangement of two sodal passages so that one is within and surrounded by the discharge of the other; also, the-formation of a chamber or enlargement in a soda-delivery passage for the purpose/ef eiiecting thereby much, if not all, that obtained in the ordinary way, by the employment of a condensingbottle, into which-'the soda is first drawn and afterward decanted.

(In the drawings illustrating an apparatus embodying'my invention, Figure l shows the said apparatus part in plan and part in horizontal/section. Fig. 2 shows a rear end elevation; and 3, a vert-ical cross section taken in the pl ne of line a z, seen in Figs. 1

The part a is divided by partition b into separate passages, which have inlets c and outlets d, which are controlled by puppetvalves e. The outlet terminations of the passages are arranged about a common center, and the valves in these outlets are worked by hand by means of the levers f, rods g, and springs h, the levers f being in the fluids which llthe passages and the rods g passing through stutling-boxes, by which leakage is prevented; or the stems of thevalves might be continued directly upward through stuiiingboxes, and the levers f might then be placed outside of the passages or pipes which convey the duids. Within the part a there is a chamber, i, which is located within the circle of or is surrounded by the outlet terminations of the sirup or iiuid passages, before referred to. This chamber has a contracted opening, 7c, Within which is the mouth of the soda-discharge-pipe Z. The chamber i and the pipe Z are supplied with soda as follows: The sodasupply pipem is located above the Sirup-pipes c and terminates in 'an upward direction,with its mouth covercdby 'a diaphragm, n, which rests on a seat, o, confined at its periphery by the piece'p, which is chambered out, so as to admitofthepieqep rvwasher q and ofthe upward movement of this and of the diaphragm An ornamental device, j, surmounts and surrounds p, serving to cover it and as a bearing or support for the upper end ofthe spindle r, which has a screw-thread formed on its lower end, which works in a nut formed in p, so that by turning r in one direction by means of the hand-wheel on its end the piece q is forced down on 'the diaphragm n on the seat o, thus stopping all apertures in o. i' in the other direction the pressure on the diaphragm from the screw is relieved, so that the soda under pressure in pipe m lifts the diaphragm and escapes over the seat o through any outlet-passages formed therein. In seat o there is one outlet-passage, s, which connects with pipe Z, and there are other outletpassages, t, which connect with the chamber i and discharge-outlet la. Upon pipe Z in chamber 'L' a diaphragm, u, may be fixed, seas nearly to extend across chamber i, the purpose of said diaphragm or collar being to check the flow of the soda toward the outlet 7c.

In the ordinary practice of preparing sodaJ beverages the sirup is first drawn into a tumbler and then a small quantity of soda is drawn into the tumbler in a iine stream, and under a full head, mixing with the sirup and making a foam or froth. let or from another a quantity of soda is drawn into a receptacle, sometimes called a ,con. (lensing-bottle, and this, without foam o froth,is decanted into the tumbler, making tl By turning Then from the same soda-outv bulk of l`the"beverage. vfNoW, by drawing the soda from pipe m -through several apertures into the chamber i the vdesired quantity of' 'soda is obtained in a quiet condition, and through'the pipe Z enough is obtained moving with sufficient forceto mingle thoroughly with the sirup, which comes from any of the sirupdischarge passages d, and to form the desired amount of foam, and thus without removal or '.changeof position of the tumbler the beverage is almost instantly prepared by the operator,

l -who has only -to rotatethe.rspindle fr 'and depress oneor more of lthe rods g. Thus-less time elapses in preparing a beverage than is required with any other apparatus with which -I am acquainted, and the beverage can be passed to the drinker with but little loss ofthe gases originally contained in the soda. Each of the passages c is connected with a separate receptacle forsirup of any desired flavor,

. cream, wines, cordials, Snc., the buttons on the rods g beingA numbered or otherwise marked for the guidance of the operator.y It will be evident that when the hand of the operator relieves a rod, g, from pressure the spring around that rod will act to close the valve vwith which `that rod isconnected. v. I claim-'v described, to admit into two or more passages and to shut off therefrom the soda supplied from a common source. l

4. The formation of a chamber in a sodadischarge pipe, so as to operate to-check the velocity of the discharge under pressure, and thus supersede the employment of the con densing-bottle, substantially as set forth.

5. The condensed arrangement of outlets so that while each is separate from the oth-ers they are all within the compass of and can each of them discharge into an ordinary drinkf ing-glass wit-hout removal thereof from a fixed position. J. H. 'BLASDELL Witnesses:
